Inov-8 believes in natural running. When running barefoot (or naturally), the foot will instinctively land on the forefoot rather than the heel. This forefoot landing causes less impact than heel striking and has been associated with reduced injury and increased speed and efficiency. Most people can make the transition to a more natural running style by gradually reducing the amount of cushioning in their shoes over time. Inov-8 offers a range of cushioning and differential (the difference in height between the heel and forefoot), named Shoc-Zone, so that you can choose the most appropriate shoe for you. All Inov-8 footwear is designed for a neutral stride. Because your heel is always lower to the ground during the running cycle, pronating and supinating are not as problematic as with other brands of trail/running shoes.
The waterproof Roclite 312 GTX is the same shoe as the Women's Roclite 275 GTX except that the 312 is built on a unisex "last" for men or women. There is slightly more room in the heel of the 312 GTX than the 275 GTX, since men tend to have wider heels than women. The 312 GTX not only offers exceptional comfort and stability, the excellent underfoot cushioning provides great shock absorption even on hard, compacted surfaces. With a roomy forefoot, the 312 GTX fits medium to wide feet and people with low to medium arches. The profile of the Roclite is ideal for people who don't want a shoe that's too high on the ankle bone, and you'll find that the toe box is deep and comfortable. The rugged outsole provides good grip on dry, muddy, and even snowy conditions. The GORE-TEX membrane prevents water from seeping in, but is also very breathable. Inov-8's patent-pending fascia-band adds to the propulsion efficiency of the running cycle by mimicking the fascia tendon, while the patent-pending meta-shank aligns with the metatarsals of the foot and allows the foot move the way nature designed.

Select the Sizing tab on the left for help selecting the correct size and fitting tips. Please note that the Roclite 312 GTX generally runs 1/2 size smaller than other styles of Inov-8s. We suggest that you order 1/2 size up from your normal shoe size. So, for example, if you normally wear a U.S. Women's size 6, we suggest ordering a U.S. Men's 5/Women's 6.5 in the Roclite 312 GTX.
